Rockdyne Enterprises is a family-owned and operated real estate investment and management company based in Los Angeles, California. Founded by Roger and Debbi Cowan, Rockdyne was built on the belief that exceptional property management begins with genuine care for the people who call our buildings home.

From the beginning, Roger and Debbi set out to create something different — a company that combines the professionalism of a seasoned property management team with the warmth and responsiveness of a family business. That philosophy still guides everything we do today.

Our “family-style” approach means we treat every tenant the way we would want to be treated: with honesty, accessibility, and respect. Whether it’s a maintenance request, a lease renewal, or simply saying hello, our team takes pride in being hands-on and available. We maintain our properties as if we lived there ourselves, ensuring clean, well-kept spaces where residents feel safe, valued, and proud to come home.

Focused primarily on Los Angeles’ Westside communities, Rockdyne Enterprises manages a portfolio of multifamily properties known for quality, comfort, and convenience. We believe that when residents feel at home, neighborhoods thrive — and that’s the heart of everything we do.

For over four decades, the Cowan family’s commitment to integrity, personal attention, and long-term relationships has shaped Rockdyne into more than just a property management company. We’re neighbors, partners, and caretakers of the communities we serve.
